An electrical power system with a source of 240Z30° Vrms, 50 Hz with the loads of lighting, cooking and
entertainment. If specification of the loads is 300 W with 400 VA lagging, 200 W with 0.88 power factor
leading and 150 VAR with 0.77 power lagging respectively, solve this completed power system by
calculating the following parameters:
c) sketch a phasor diagram to show all load currents and source voltage relationship
d) capacitance, C across the load if the new load power factor is 0.95 lagging
